I am spending lot of time with development coin battery powered devices.
I have full desk of batteries, I try solve this mess with 3D printed battery holder. It is good for organisation but after time I see that it is just only dust collector. If I need charged this chaos I used some USB hubs, then I have desk full with cables and chargers.
Here is solution for 2 battery chemistry.
- 6 independent charging channels for LIR2032 battery with 6 charging controllers
- charging feedback with 12 LEDS
- 6 independent charging channels for ML2032 (LMR2016) battery with trickle charging regulator
- ML part have no full charge feedback, just leave battery about 24 hours or more in charger
- powered with single micro USB connector
10x10 cm
-Both charging block are designed to keep specifications for LIR and ML charging
I sold about 500pcs of my chargers and nobody report problem. You can found on ebay cheap coin cell chargers but they parameters are far away manufacturer spec.
Try search on ebay directly for LIR2032 an ML2032 batteries, they have different advantages, voltage and chemistry.
hi, I seling my chargers with similar price :) https://www.tindie.com/stores/bobricius/ maybe eleksmaker charger is better but they battery holder is disaster.
